Why SiC Devices Are Ideal for Level 3 EV Charging Applications

On September 24, 2019 in All, Power, Wide Bandgap by Robert Huntley

Charging an EV can be a lengthy process, however, Level 3 “fast” DC charging techniques promise much faster charging capabilities that reduce charging times to minutes instead of hours. This efficiency relies on high-speed power conversion, for which new wide-bandgap technologies are well suited.

SiC Devices Usurp Si MOSFETs and Diodes in Servers, Motors, EVs

On October 1, 2018 in All, Power, Wide Bandgap by Bill Schweber

Switching devices—both transistors and diodes—based on silicon-on-carbide (SiC) are redefining capabilities of power-related circuits. These offer far better efficiency and range than today’s best silicon-only MOSFETs, IGBTs, and diodes, and are already in widespread use in top-tier data centers and server farms.

Engineering for Space: Many Challenges, Various Solutions

On October 6, 2017 in All, Robotics, Wide Bandgap by Sylvie Barak

High-performance, zero margin for error, extreme environments, and more are just some of the high-stakes challenges that space engineers face. New materials, louvres, space hardening, Whipple shielding, and artificial intelligence (AI) are just some of the ways space design challenges are addressed.

GaN the Giant Killer?

On January 28, 2014 in Wide Bandgap by Barry Manz

Gallium nitride (GaN) has evolved from a promising laboratory curiosity to a major force in RF power generation in less than a decade. Much has been made of its inherent advantages, leading to projections that it will displace gallium arsenide and silicon LDMOS. However, for a variety of reasons GaN is more likely to complement its more entrenched rivals than displace them.
